Thanks NIKHILRAJ. I followed your advise, download GC-Prevue and kicked it around for about 10 minutes. Looks like a handy tool. However, seems like you need the $495-00 GC-PreviewPlus in order top manipulate the image :cry:
I have completed the layout of a pcb in Kicad. I make my owm pcb's using the photo resist method, so I normally print the pcb image on a transparency for use in a UV box.
This time round, I want to print a couple of images of the pcb on the same transparency. This will allow me to etch a couple...
This charger will destroy a battery in a potentially dangerous way, since there is no current limiting. A battery that is completely run down, will draw a large amount of current which will cause the battery to overheat.
A transistor is required to measure a current sense resistor and pull the...
Is there a catalog or reference available somewhere, which lists the part number AND device type? I find it very tedious, when looking for a device that meets certain requirements. For instance, I am looking for a N-channel JFET with a pinch-off of -9V, Id>400mA etc. I suppose I could type all...
Kicad errors
Thanks for the reply Mike. That was also my thought, that the pin names are different. I made a copy of the footprint and made the names the same. I just did it again, importing the netlist into the pcb gives the following:
[TO220_VERT2]
Module [U1]: Pad [VI] not found
Module [U1]...
Ok, that makes more sense. So, using that example, a 0.0005ohm resistor will dissipate 0.008W, when measuring 4A? I can live with that.
Thanks for the quick reply.
I am in the process of designing an intelligent battery monitor. Its for an RV where a freezer will be running off a 12V lead acid deep cycle battery. Just monitoring the voltage is not enough, since it will report a run down battery after the fact. I want to monitor the current draw of the...
Kicad errors
I am trying out Kicad for the first time. I've found that once I got my head around the seperate component and footprint libraries it all makes sense. But I've got a couple of issues I can't seem to figure out.
(I can't get the image to show in the right place in this post?)...
The important thing to look for is the "holding torque" of the stepper motor. With such a large weight, you will have to work out the torque that's required to move the weight, as well as to keep it stationary. The required torque will be determined by the distance of the weight from the center...
Re: AVR UART problem
First place to start looking, would be the fuse bits. Make sure that fuses are set correctly for the type of crystal you are using.
The RC5 protocol is quite common in remote controls, but off course there are many different protocols. Here is a good description of RC5. Off course this won't help much if you don't have an RC5 remote. I would suggest building a simple receiver circuit, that would allow you to analyze the...
Re: [HELP] precise 1 second
Set the prescaler to 1024 and keep a 16bit counter in the interrupt routine to count to 10800(0x2a30), which will be 1 second exactly.
